I am having a problem creating an equation that would me the correct value for X. It is as follows:
Bob leaves on his bike, traveling north. At the same time, Sue leaves by car, traveling south. Bob and Sue leave from the same location. After 30 minutes, they are 35km apart. Suppose that x represents Bob's speed and (2x + 10) represents Sue's speed, both in kph. Find the speeds at which Bob and Sue travel.
If anyone has any suggestions, I'd appreciate it.
